Abstract:
BACKGROUND:At present, it is a hot spot to study the relationship between digit or phalange length ratios and athletic ability. However, the results from various studies cannot be verified each other because there are controversies about the research objects and the research technique in the area. Therefore, it is necessary to point a right direction for the research in this field. OBJECTIVE:To explore the relationships of digit and phalange length ratios to athletic ability and the existing problems by literature search strategies and logic thinking methods. METHODS:A computer-based online search was conducted in Elsevier Science-direct, PubMed, EM, CNKI, and CJFD databases by using the key words of“digit length ratio, 2D:4D, phalange length ratio, athletic ability”from 1990 to 2015. The language was limited to both Chinese and English. 358 relevant articles were screened, and 42 eligible articles were included final y. RESULTS AND CONCLUSION:Currently, studies show that there are some relationships between digit phalange length ratio or phalange length ratio and athletic ability. There are controversies about the research results due to the diverse study methods and techniques. It is necessary to define the digit phalange length ratio or phalange length ratio in the human study. The most advanced techniques should be considered to reduce the measurement bias. Moreover, multi-angle, multi-level studies should be performed to reveal the relationship of digit phalange length ratio or phalange length ratio to athletic ability. Human digit phalange length ratio or phalange length ratio, particularly 2D:4D can reflect the aerobic exercise capacity of athletes.
